When the access history (13A) is stored, the content of the WEB page is first divided into information blocks B1 to B5 as shown in FIG. Then, the zoom count [zoom_cnt] for each of the information blocks B1 to B5 is read, and the block layout in the WEB page is in the order [B2-> in descending order of the zoom count [zoom_cnt] as shown in FIG. B5 → B4 → B3 → B1].

  As shown in FIG. 8B, the WEB page in which the arrangement of the information blocks B1 to B5 is sorted in the descending order of the zoom count [zoom_cnt] is further stored in the access history (13A). The horizontal size of each of the information blocks B1 to B5 is adjusted in accordance with the screen horizontal size [width_disp] of the display unit 25 of [user_id], written to the virtual frame buffer 12B, and transferred to the client device 20.

  Next, operations of the server device 10 and the client device 20 in the server-based computing system having the above configuration will be described.

  FIG. 9 is a flowchart showing a control process of the client device 20 in the server-based computing system.

  FIG. 10 is a flowchart showing a control process of the server apparatus 10 in the server-based computing system.

  When the client device 20 is turned on and its operation is started, a connection authentication request is transmitted to the server device 10, and when the connection with the server device 10 is established, the client device 20 Initial setting data (user ID, minimum font size, display screen size) stored in advance in the storage unit 23 is read and transmitted to the server device 10 (step C1).

  When the server device 10 receives the initial setting data (user ID, minimum font size, display screen size) transmitted from the client device 20 after the connection with the client device 20 is established (step S1 ( YES)), the received user ID [user_id], minimum font size [minfont], and display screen size [width_disp × hight_disp] are stored in the access history storage unit 13A (see FIGS. 6 and 7) in the storage unit 13. (Step S2).

  In response to an input event from the client device 20 (steps C8 and C9), the WEB browser program of the server device 10 is activated (steps S12 and S13), and the WEB in which the URL desired by the user is specified in the client device 20 If it is determined that a page request operation has been performed (step C4 (YES)), a request event for the WEB page is transmitted to the server device 10 (step C5).

  When the server device 10 receives the WEB page request event transmitted from the client device 20 (step S3 (YES)), the WEB server 30 is accessed according to the URL specified in the request event. A request command for the WEB page is transmitted (step S4).

  In response to the web page request command from the server device 10 to the web server 30, when the web page data is received from the web server 30 (step S5 (YES)), the received web page data is received. 11 is performed (step SA), and WEB page screen data to be displayed on the client device 20 is generated and written to the virtual frame buffer 12B (step S6). 20 (step S7).

  When the client device 20 receives the screen data of the WEB page transmitted from the server device 10 (step C2 (YES)), the received screen data of the WEB page is written into the frame buffer 22A, and the display unit 25 (step C3).

  In this way, the screen data of the WEB page desired by the user in the client device 20 is acquired by the server device 10, transmitted and transferred from the server device 10 to the client device 20, and displayed. When a user-desired information block Bn is designated and zooming (enlargement) is instructed (step C6 (YES)), a coordinate position corresponding to the designated information block Bn and a zoom request are transmitted to the server device 10. (Step C7).

  When the server device 10 receives the coordinate position and zoom request corresponding to the information block Bn transmitted from the client device 10 (step S8 (YES)), the user ID [user_id] and the current acquisition of the client device 10 are received. The zoom count [zoom_cnt] of the corresponding block ID [block_id] in the block data 13A2 (see FIG. 7) of the access history storage unit 13A associated with the URL [url] of the WEB page in the middle is counted up, and the final The access date [last_acc] is updated (step S9).

  Then, the information block Bn requested to be zoomed from the client device 20 corresponds to the display screen size [width_disp × hight_disp] of the client device 20 stored as the user data 13A3 of the access history storage unit 13A, for example, as shown in FIG. As shown in FIG. 5, the zoom process is performed and the result is written into the virtual frame buffer 12B (step S10).

  Then, the WEB screen data of the information block Bn subjected to the zoom process is transmitted to the client device 20 (step S11).

  Here, in the control process of the server device 10, when the WEB page data received from the WEB server 30 is generated and transferred as display screen data for the client device 20 (steps S 5 to S 7), the process proceeds to step SA. WEB page data layout change processing executed in this way will be described.

  FIG. 11 is a flowchart showing a layout change process accompanying the control process of the server device 10 in the server-based computing system.

  When the layout change process is started, first, the memory 13A1 (13A1) of the access history storage unit 13A associated with the user ID [user_id] of the client device 10 and the URL [url] of the currently acquired WEB page. The access count [acc_cnt] to the WEB page in FIG. 6 is read, and whether or not there is at least one access, that is, the block data 13A2 related to the WEB page shown in FIG. 7 has already been generated. It is determined whether or not (step A1).

  If it is determined that the number of accesses [acc_cnt] to the currently acquired WEB page is at least one (step A1 (YES)), the block data 13A2 in the access history storage unit 13A (see FIG. 7). The zoom count [zoom_cnt] of each block ID [block_id] is read (step A2).

  Then, for example, in the order in which the past zoom count [zoom_cnt] of each information block constituting the currently acquired WEB page read in step A2 is large, that is, in the descending order of user attention, for example, as shown in FIG. As described above, the information blocks B1 to B5 are sorted as [B2-> B5-> B4-> B3-> B1] (step A3).

  Then, the block screen size [width_size × hight_size] and the used font size of each of the information blocks B1 to B5 constituting the WEB page are acquired, and the block screen size [width_size × hight_size] is stored in the access history storage unit 13A. It is stored in association with each block ID [block_id] in the block data 13A2 (see FIG. 7), and the used font size is temporarily stored in the storage unit 13 (step A4).

  Here, for each information block [B2-> B5-> B4-> B3-> B1] in the WEB page sorted in step A3, the processing after step A5 is sequentially executed.

  First, it is determined whether or not the information in the block Bn is text data for the target information block Bn in the WEB page (step A5).

  When it is determined that the information in the block Bn is text data (step A5 (YES)), the client device 20 stored as user data 13A3 (see FIG. 6) in the access history storage unit 13A. The screen horizontal ratio obtained by dividing the screen horizontal size [width_disp] of the display unit 25 by the horizontal size [width_size] of the current information block Bn stored as the block data 13A3 (see FIG. 7) of the access history storage unit 13A R is calculated (step A6).

  Then, among the font sizes of the information blocks [B2-> B5-> B4-> B3-> B1] temporarily stored in step A4, the font size of the current information block Bn is multiplied by the screen aspect ratio R. It is determined whether or not the value is equal to or larger than the minimum font size [minfont] of the client device 20 stored as the user data 13A3 (see FIG. 6) of the access history storage unit 13A (step A7).

  If it is determined that the font size is equal to or larger than the minimum font size [minfont] (step A7 (YES)), the font size of the current information block Bn is set to the horizontal ratio R to the display screen of the client device 20. The font size is multiplied (step A8).

  Then, a new line is inserted into the layout of the text data composing the current information block Bn according to the changed font size at the position corresponding to the screen horizontal size [width_disp] of the client device 20, so that the screen horizontal It is shaped to fit within the size [width_disp] (step A10).

  On the other hand, in step A7, it is determined that the value obtained by multiplying the font size of the current information block Bn by the horizontal ratio R with respect to the display screen of the client device 20 is less than the minimum font size [minfont] of the client device 20. (Step A7 (NO)), that is, for example, the horizontal size [width_size] of the current information block Bn is larger than the screen horizontal size [width_disp] of the client device 20 (particularly in the case of the mobile phone 20M). When the font size of the block Bn is substantially reduced and becomes smaller than the minimum font size [minfont], the font size of the current information block Bn is changed to the minimum font size [minfont]. (Step A9).

  Then, a line break is inserted at a position in accordance with the screen horizontal size [width_disp] of the client device 20 in the layout of the text data constituting the current information block Bn by the changed minimum font size [minfont]. Then, it is shaped to fit within the screen horizontal size [width_disp] (step A10).

  Thereafter, for each information block [B2-> B5-> B4-> B3-> B1] in the WEB page sorted in the step A3, the shaping process is sequentially performed in accordance with the screen horizontal size [width_disp] of the same client device 20. Is executed (steps A5 to A10), for example, the screen data of the WEB page as shown in FIG. 8B is generated and written to the virtual frame buffer 12B (step S6). It is transferred (step S7) and displayed on the display unit 25 (step C2 → C3).
